Vic from VR designs sent me a new exe file for DC:WtP. It is in a zip file, but Windows won't let me unzip it. The Windows Security Window always pops up and says that this file is harmful. How can you defeat this warning?

Get rid of whatever is reporting the error (e.g., disable the dastardly thing).
